The objective of this Phase-II effort is to build and deliver a high-speed laser system for performing particle-image velocimetry (PIV) and planar laser-induced fluorescence (PLIF) of OH at rates of 5 to 10 kHz in augmentor test facilities. This state-of-the-art laser system will allow velocity and 2-D flame radical measurements for understanding the complex spatio-temporal development of instab ...

DESCRIPTION (provided by applicant): The broad long-term goals of this project are to develop more powerful proteomics detection technology with greatly improved sensitivity, that will reveal the global patterns of biologically stimulated changes (differen tial detection) in protein levels, posttranslational modifications and enzyme activities simultaneously (using 6-12 channel multicolor fluoresc ...

The most significant hardware costs on a missile interceptor propulsion system are associated with the thrusters, for which there are typically four divert thrusters and four, six, or eight attitude control thrusters per interceptor. The largest contributor to the thruster cost is the integrated valve/injector. Integration of the valve and injector into a single body provides the benefits of low d ...

The U.S. Navy uses a cold-hole expansion method for increasing the fatigue life of primary aircraft structures at fastener locations. The derived benefit results from compressive stresses concentrated in the metal near the perimeter of the cold worked hole. The objective of this Phase II proposal is to develop portable, light weight, quality assurance tools, based upon Eddy Current technology, t ...

Critical large bearings in the F-35 thrust vector system must operate with absolute reliability under high loads, high heat and corrosive attack from salt air and fluorinated lubricant at elevated temperatures. A unique patented Filtered Arc Plasma Source Ion Deposition (FAPSID) process developed by Arcomac Surface Engineering will deposit an atomically bonded, multiple layered, integrated coatin ...

Flow control using high-frequency actuation to reduce acoustic and vibrational loading from weapons bays and sensor apertures requires a diagnostic approach that can capture instantaneous flowfield data at rates of several kHz. Moreover, large wind tunnel facilities suffer the difficulty of particle seeding for techniques such as Particle Imaging Velocimetry (PIV). The opportunity addressed by t ...

Accurate observations and forecasts of meteorological conditions in the battlespace are of extreme importance to the most effective employment of military assets. In many instances, it is not possible to gather in-situ meteorological data by routine means such as sounding balloons carrying radiosondes. There is a need to provide a means by which such data may be gathered with the requisite accur ...

In Phase I of this project, FTG researchers showed that complete and uniform coatings of metal-coated particulates provide a mechanism for improving particle distribution, enhancing mechanical properties of fabricated components, and significantly improving the performance of reactive materials. This permits the creation of fully dense and high-quality MMCs for the production of bulk materials/coa ...

Improved observations of the battlespace are of key and growing importance in today’s combat environment. UAVs are making key contributions in this area, and sensor improvements are a key part of increasing UAV capabilities. However, all sensors are subject to degradation under detrimental environmental conditions. Adding a sensor system to UAVs that enables the real-time identification and a ...

The lack of proper estimation of air loads encountered during transient maneuvers introduces excessive design conservatism. A reduced fidelity CFD methodology based on momentum source (Rot3DC) and a comprehensive analysis code (RCAS) were coupled in Phase I to validate the ``proof-of-concept'' that such system is capable of rapidly analyzing steady and transient maneuvers. The tightly coupled sys ...
